Film capacitors have been continuing to gain significance due to their varied application fields and simple working principle. ECH-U1153GC9 is one of the top-range self-healing film capacitors with exceptional properties for AC grid applications, offering excellent protection against power surges. It is a self-contained or monoblock film capacitor. This capacitor consists of a metallic housing for individual wound metallized PP or PET-film capacitors. There is also a built-in discharge resistor, thermal fuse, and a voltage indicator, making it a secure, reliable, and safe component. The self-healing characteristic of this component means that the capacitor can tolerate very high voltage stress and the discharge resistor will blow the capacitor before any capacitor damage occurs.

The ECH-U1153GC9 offers an excellent combination of safety, low costs and small size. It is a particularly good choice for medical and power applications where high reliability and safety against environmental hazards, especially AC power surges, are a must. It is also suitable for many other applications, such as automotive, industrial and military use. All of these applications must be in compliance with IEC-62133 and UL-910 standards.

ECH-U1153GC9 has a working principle that is quite simple. It works on the principle of dielectric absorption, in which the dielectric medium absorbs part of the energy of an electrical field. The dielectric property of the medium changes with increased electric field strength, leading to an increase in the capacitance. After a certain level is reached, the capacitance can no longer increase and energy is absorbed by the dielectric as heat energy. This heat energy is then dissipated from the capacitor and the capacitor is considered to have self-healed. The self-healing process of the ECH-U1153GC9 ensures that the capacitor will perform with the same excellent and reliable protection even after multiple instances of AC power surges.

ECH-U1153GC9 also offers reliable safety protection against environmental hazards that can affect a capacitor’s performance. It provides good protection against dust, moisture and vibration, which can lead to a capacitor’s failure in harsh and extreme environments. This means that it is suitable for industrial and military use, where durability is a must. The ECH-U1153GC9 is also compatible with a wide range of temperatures, ranging from -40°C to +85°C, and with a wide variety of voltages, from 340 Volts AC to 400 Volts AC.

The ECH-U1153GC9 is designed to offer the highest level of performance and protection. It is safe and reliable, and has been designed to provide the best possible protection against power surges. This capacitor is also designed to offer low cost, small size and high reliability in some of the most demanding applications.
